Accelerate Your mac can help you with all that. http://www.xlr8yourmac.com/
But if you have the skills to change out some socket LGA 771 xeons
Here is what you need to do:
1 Download the MacPro firmware tool from: http://forum.netkas.org/index.php/topic,1094.0.html
2 Flash your Mac Pro 1, 1 to a 2, 1. The machines are identical as far as hardware. The flash upgrades your Mac Pro firmware to a 2008 Firmware and makes it compatible with Lion and Snow Leopard. Its super easy and wont hurt your machine at all and it will still run with the 2,1 Firmware on your stock processors and you can flash it back to a 1, 1 if you want just as easy. Note: when you flash the firmware you will need to restart your machine 2 times to get the second Xeon to show up but it will and does every time. So dont freak if you dont see the second processor on the first reboot.
It is also a good idea to reset pram command+option+p+r keys on reboot after the firmware flash.
3 Go to: http://serversupply.com
The cheapest place on the web to purchase X 5365 3.0 Ghz Clovertown xeons. Currently ranging from $148.00 to 210.00 per X 5365 Xeon New. Buy two. They will send you a matched set if you buy two. There are only 3 versions of the X 5365's. My sSPEC on my two are SLAED. It is very important there the same sSPEC. It is printed right on the top of the Xeon Chip itself.
4. Go Here for tutorial on disassembly of your Mac Pro and installation of your new xeons: http://www.anandtech.com/show/2079/3
5. Install Your new processors and reassemble your machine.
6. Enjoy 4 more cores! For a total of 8 cores. My machine stock was a dual 3.0 Ghz dual core. With woodcrest xeons.
Heres some picts of my system info.
Oh one more thing I almost forgot you will need a really long 9" 3mm hex key wrench which you can buy on amazon for about 4 bucks, to remove the Xeon heat syncs.
Also use Artic Silver Heat sync paste also available at amazon for your heat syncs... After a thorough cleaning of the old paste off your heat syncs for your new Xeons.
